| GenParticle * HepMC::GenEvent::barcode_to_particle | ( | int | barCode | ) | const [inline] |
assign a barcode to a particle
Each vertex or particle has a barcode, which is just an integer which uniquely identifies it inside the event (i.e. there is a one to one mapping between particle memory addresses and particle barcodes... and the same applied for vertices).
The value of a barcode has NO MEANING and NO ORDER! For the user's convenience, when an event is read in via an IO_method from an indexed list (like the HEPEVT common block), then the index will become the barcode for that particle.
Particle barcodes are always positive integers. The barcodes are chosen and set automatically when a vertex or particle comes under the ownership of an event (i.e. it is contained in an event).

delete all vertices owned by this event
deletes all vertices in the vertex container (i.e. all vertices owned by this event) The vertices are the "owners" of the particles, so as we delete the vertices, the vertex desctructors are automatically deleting their particles.
